Oh dear, I am terrible at giving tips but like... I watched Zeros guide on Cpt. Faclon and he said to use alot of Up-Airs so like... do that, I guess? lol
Also, beware of the Gordos, unless you have a super quick move that can reflect them, don't bother; just shield. Like, letting DDD do his "thing" and then going in to kick the fat birds ass can probably work.
I'm having trouble with Yoshi and Ness, any tips?
